This patch updates the MIPI DBI driver to use drm_device.debugfs_root instead of drm_minor for creating debugfs files. The debugfs setup is now done earlier in probe(), before drm_dev_register(), and the drivers can avoid using the .debugfs_init callback.
This is an initial version, and only a few drivers are updated for now. I noticed that some newer drivers or patches still use drm_debugfs_create_files(), which relies on drm_minor. I was wondering if there is a specific reason for this, or if there's a plan to switch to drm_debugfs_add_files? I can send patches to update more drivers if that helps. This patch helps move toward the debugfs cleanup task listed here: https://docs.kernel.org/gpu/todo.html#clean-up-the-debugfs-support Looking forward to your feedback.
